Log#
The module writes request logs in the specified format. Default stream, server Sets the If either the Caution The buffer size must not exceed the size of an atomic write to a disk file. For FreeBSD this size is unlimited. When buffering is enabled, the data will be written to the file: if the next log line does not fit into the buffer; if the buffered data is older than specified by the flush parameter; when a worker process is re-opening log files or is shutting down. If the gzip parameter is used, then the buffered data will be compressed before writing to the file. The compression level can be set between 1 (fastest, less compression) and 9 (slowest, best compression). By default, the buffer size is equal to 64K bytes, and the compression level is set to 1. Since the data is compressed in atomic blocks, the log file can be decompressed or read by "zcat" at any time. Example: Important For gzip compression to work, Angie must be built with the zlib library. The file path can contain variables, but such logs have some constraints: the user whose credentials are used by worker processes should have permissions to create files in a directory with such logs; buffered writes do not work; the file is opened and closed for each log write. However, since the descriptors of frequently used files can be stored in a cache, writing to the old file can continue during the time specified by the open_log_file_cache directive's valid parameter. The if parameter enables conditional logging. A session will not be logged if the condition evaluates to "0" or an empty string. Specifies log format. The For For Default stream, server Defines a cache that stores the file descriptors of frequently used logs whose names contain variables. The directive has the following parameters: sets the maximum number of descriptors in a cache; if the cache becomes full the least recently used (LRU) descriptors are closed sets the time after which the cached descriptor is closed if there were no access during this time; by default, 10 seconds sets the minimum number of file uses during the time defined by the sets the time after which it should be checked that the file still exists with the same name; by default, 60 seconds disables caching Usage example:Configuration Example#

escape parameter allows setting json or default
characters escaping in variables, by default, default escaping is used.
The none value disables escaping.default escaping, characters """, "\", and other characters with
values less than 32 or above 126 are escaped as "\xXX". If the variable value
is not found, a hyphen "-" will be logged.json escaping, all characters not allowed in JSON strings will be
escaped: characters """ and "\" are escaped as "\"" and "\\", characters
with values less than 32 are escaped as "\n", "\r", "\t", "\b", "\f", or
"\u00XX".open_log_file_cache#
